<p>This class is used to construct vertical box layout objects. See
<a href="qboxlayout.html">QBoxLayout</a> for details.</p>
<p>The simplest use of the class is like this:</p>
<pre class="cpp">
     <span class="type"><a href="qwidget.html">QWidget</a></span> <span class="operator">*</span>window <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qwidget.html">QWidget</a></span>;
     <span class="type"><a href="qpushbutton.html">QPushButton</a></span> <span class="operator">*</span>button1 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(<span class="string">"One"</span>);
     <span class="type"><a href="qpushbutton.html">QPushButton</a></span> <span class="operator">*</span>button2 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(<span class="string">"Two"</span>);
     <span class="type"><a href="qpushbutton.html">QPushButton</a></span> <span class="operator">*</span>button3 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(<span class="string">"Three"</span>);
     <span class="type"><a href="qpushbutton.html">QPushButton</a></span> <span class="operator">*</span>button4 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(<span class="string">"Four"</span>);
     <span class="type"><a href="qpushbutton.html">QPushButton</a></span> <span class="operator">*</span>button5 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(<span class="string">"Five"</span>);

     <span class="type">QVBoxLayout</span> <span class="operator">*</span>layout <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QVBoxLayout</span>;
     layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(button1);
     layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(button2);
     layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(button3);
     layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(button4);
     layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(button5);

     window<span class="operator">-</span><span class="operator">&gt;</span>setLayout(layout);
     window<span class="operator">-</span><span class="operator">&gt;</span>show();
</pre>
<p>First, we create the widgets we want in the layout. Then, we
create the QVBoxLayout object and add the widgets into the layout.
Finally, we call <a href="qwidget.html#setLayout">QWidget.setLayout</a>() to install the
QVBoxLayout object onto the widget. At that point, the widgets in
the layout are reparented to have <tt>window</tt> as their
parent.</p>
